[PATCH 1/3] soundwire: qcom: drop unneeded DAI .set_stream callback

[Krzysztof Kozlowski]

Qualcomm Soundwire controller drivers do not support multi-link setups,
so DAI .set_stream() callback will not be used.  What's more, if called
it will overwrite the sdw_stream_runtime runtime set in DAI .startup
(qcom_swrm_startup()) causing issues (unsupported multi-link error) when
two Soundwire controllers are passed as codec DAIs.
